Brain and personality bases of insensitivity to infant cues in neglectful mothers: An event-related potential study / María José RODRIGO in Development and Psychopathology, 23-1 (January 2011)  

Public ISBD [article]  inDevelopment and Psychopathology > 23-1 (January 2011) . - p.163-176 Titre : Brain and personality bases of insensitivity to infant cues in neglectful mothers: An event-related potential study Type de document : Texte imprimé et/ou numérique Auteurs : María José RODRIGO, Auteur ; Inmaculada LEON, Auteur ; Ileana QUINONES, Auteur ; Agustín LAGE, Auteur ; Sonia BYRNE, Auteur ; María Antonieta BOBES, Auteur Année de publication : 2011 Article en page(s) : p.163-176 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This investigation examined the neural and personality correlates of processing infant facial expressions in mothers with substantiated neglect of a child under 5 years old. Event-related potentials (ERPs) were recorded from 14 neglectful and 14 control mothers as they viewed and categorized pictures of infant cries, laughs, and neutral faces. Maternal self-reports of anhedonia and empathy were also completed. Early (negative occipitotemporal component peaking at around 170 ms on the scalp [N170] and positive electrical potential peaking at about 200 ms [P200]) and late positive potential (LPP) components were selected. Both groups of mothers showed behavioral discrimination between the different facial expressions via reaction time and accuracy measures. Neglectful mothers did not exhibit increased N170 amplitude at temporal leads in response to viewing crying versus laughing and neutral expressions compared to control mothers. Both groups had greater P200 and LPP amplitudes at centroparietal leads in response to viewing crying versus neutral facial expressions. However, neglectful mothers displayed an overall attenuated brain response in LPP that was related to their higher scores in social anhedonia but not to their empathy scores. The ERP data suggest that the brain's failures in the early differentiation of cry stimuli and in the sustained processing of infant expressions related to social anhedonia may underlie the insensitive responding in neglectful mothers. The implications of these results for the design and evaluation of preventive interventions are discussed.

Neglectful maternal caregiving involves altered brain volume in empathy-related areas / María José RODRIGO in Development and Psychopathology, 32-4 (October 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-4 (October 2020) . - p.1534-1543 Titre : Neglectful maternal caregiving involves altered brain volume in empathy-related areas Type de document : Texte imprimé et/ou numérique Auteurs : María José RODRIGO, Auteur ; Inmaculada LEON, Auteur ; Lorna GARCÍA-PENTÓN, Auteur ; Juan Andrés HERNÁNDEZ-CABRERA, Auteur ; Ileana QUINONES, Auteur Article en page(s) : p.1534-1543 Langues : Anglais (eng) Mots-clés : empathy  maternal neglect  mother–child interaction  volume alterations  voxel-based morphometry Index. décimale : PER Périodiques Résumé : The maternal brain undergoes adaptations to sensitive caregiving that are critical for infant well-being. We investigated structural alterations associated with neglectful caregiving and their effects on mother-child interactive behavior. High-resolution 3D volumetric images were obtained on 25 neglectful (NM) and 23 non-neglectful control (CM) mothers. Using voxel-based morphometry, we compared differences in gray and white matter (GM and WM, respectively) volume. Mothers completed an empathy scale and participated with their children in a play task (Emotional Availability Scale, EA). Neglectful mothers showed smaller GM volume in the right insula, anterior/middle cingulate (ACC/MCC), and right inferior frontal gyrus and less WM volume in bilateral frontal regions than did CM. A greater GM volume was observed in the right fusiform and cerebellum in NM than in CM. Regression analyses showed a negative effect of greater fusiform GM volume and a positive effect of greater right frontal WM volume on EA. Mediation analyses showed the role of emotional empathy in the positive effect of the insula and right inferior frontal gyrus and in the negative effect of the cerebellum on EA. Neglectful mothering involves alterations in emotional empathy-related areas and in frontal areas associated with poor mother-child interactive bonding, indicating how critical these areas are for sensitive caregiving.
